Laptop power management modes [Copy link]

Laptops include the following common advanced power management functions: 　　Operation mode: Operation mode can control processor speed or set power saving timer. 　　Standby mode: When the user does not operate the machine for a short period of time, the machine can enter standby mode. 　　Suspend mode: When the user leaves the computer for a long time, the machine can enter suspend mode. 　　Hibernation mode: When the user does not use the computer for a few days, the laptop can enter hibernation mode. 　　Take Toshiba laptop as an example. It can be set in three modes. Its power supply modes are standard mode, power saving mode and full mode. Through the cyclic conversion of the three modes, the brightness of the display screen and the voltage and power consumption of each component can be adjusted to meet the working needs in different environments. 　　Using power management program to achieve power saving control is also a very effective and feasible method. At present, most laptops have generally adopted this intelligent power saving management technology. It uses software methods to control the power consumption status of each major power-consuming component, and reduce or even stop the power supply to the components that are not working temporarily. If the management program detects that the user has not used the keyboard for a certain period of time, it will automatically turn off the display screen background; if it detects that the hard disk is not used, it will turn off the hard disk power supply. In the ready-to-work state, the CPU clock stops, the display and hard disk power are cut off, and the power consumption can be reduced by more than 70%.
